STORE-FRONT.

SPECIFICATION forming part of Letters Patent No. 795,004, dated July 18, 1905. Application filed October 1, 1904. Serial No` 226,826.

To (1J/Z 71171/0171/ it mfr/ty 0071/007477..-

Be it known that I, FREDERICK W. VON OVEN, a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Store-Fronts, of which the following is a specification.

My invention relates to an improvement in the construction more particularly of the base portion of the metal window-frame in a storefront, my more important objects being to provide a construction of store-front whereby the glass shall be effectively protected against fracture, ventilated to prevent it from frosting', and whereby moisture on the inner surface of the glass and also on the display platform or ledge at the base of the glass shall be drained off. In the accompanying drawings, Figure l is a view in front elevation of a portion of a store-front embodying` myimprovement; Fig. 2, a section taken at the line 2 on Fig. 1 viewed in the direction of the arrow and enlarged; Fig. 3, a broken section taken at the line 3 on Fig. 2 and viewed in the direction of the arrow, but with the window pane omitted to disclose its seat; and Fig. 4, a section taken at the line 4 on Fig. 2 and viewed in the direction of the arrow.

A denotes as a whole the metal frame of a store-front represented as holding the usual large panes B of expensive glass through which to view the display of goods in the store and which it is therefore desirable to keep clear from frost in cold weather and from moisture on its inner surface and the. expensive character of which renders important the matter of avoiding its fracture by the unequal expansion and contraction of the metal frame in which it is set. The base A or sill-bar of the frame is a hollow elongated casting formed with an inner side n, of substantially Z shape in cross-section with reinforcing-ribs b of general inverted-L shape at intervals extending' from its upper edge to the outer edge of the ofl'- set section and an outerl side a', vertically narrower than the side a and which may be shaped, as shown, to present an ornamental face or otherwise, with a fiat top a? projecting toward.

the side a to the ribs to which it is joined in casting at a depending flange L, the top a2 being on a lower plane than the upper edge of the side a, while the lower edges of the two sides of the frame-base are in the same plane and are spaced apart at intervals by lugs c, cast to extend joiningly between them. The

hollow base A is thus open at top (at the inside) and bottom, (at the outside,) the ribs and lugs c, which are coincident in pairs, affording air-passages between the pairs.

Below the base A an extension A2 of the frame is shown with panels d covering the openings therein; but that portion of the frame structure is not necessary to my invention.

A pane of glass Bis set to rest at its lower edge upon the top a2 near the inner edge of the latter and is confined at its side edges and its upper edge by the sides and top of the frame A, which are in the form of Tbars, like that shown at e in Fig. 3, connected together in a usual or any suitable manner to form the frame, the T-rails of the frame sid es being screwed or bolted or otherwise fastened toward their lower ends to the back of the base A. Face or stop bars f are fastened, as by screws g, at suitable intervals to the faces of the T-`bars e to cover them, with a narrower bar f interposed lengthwise and centrally between the face of each T-bar and the back of each face-bar to space them apart and afford the usual confining grooves or recesses for the respective edges of the glass. For confining a pane B along its lower edge a stopbar /L is provided, having a depending lip /L on its outer edge and a flange 71,2 depending at its inner edge. This stop-bar is so placed on the base-top a2 as to abut the lip 71, against the outer edge of said top, with the bar bearing at its iiange z/Z on the upper surface thereof, in which position the bar /1l is fastened, as by screws L. The pane is thus confined along its lower edge portion between the ribs b and the flange it, which maintains permanently the same relation to the surface of the glass, being held against creeping or uneven bearing against it and consequent tendency to fracture it by engagement of the lip /L with the top edge.

An angle-iron c" is representedin Fig. 2 as IOO IO thus provided permits the free circulation of air from the outside through the vframe-base A from below the pane-seat thereon, as indicated by arrows, to thc inner side thereof behind said seat, where the air-currents are directed upward along the inner surface of the glass, with the effect of maintaining' the same temperature on both surfaces thereof and preventing frosting' of the inner surface or clouding it with moisture, as thc case may 2O be, with resultant impairment of the desired transparency of the glass. Any moisture on the inner surface of the pane, as from wash-l ing it, may run down it and escape through the hollow Ventilating frame-base, thus preventing accumulation thereof on the platform or running into the store, where it might do damage to goods under display and would require to be mopped up. A further and incidental advantage due to my improvement is that of enabling the cloth (not shown) usually employed for covering the platform C to be placed with its forward edge fitting close up to the glass by extending it over the tops of the ribs thereby concealing from View the entire platform-surface behind the glass, and

also the trough (not shown) sometimes provided to catch the water running down the pane in washing it.

The particular details of construction and combinations of .part-s shown and described may be variously modified by those skilled in the art without departure from my invention. Hence I do not intend to be understood as intending to limit it thereto.

What I claim as new, and desire to secure by Letters Patent, is*

1. A hollow metal sill-bar adapted to seat on its top a window-pane and open to the circulation of air through' it from its outer side below said top to its inner side behind the same, and a stop-bar for confining said pane at its lower edge, having' an outer depending lip and secured on said bar to engage said lip with the outer edge thereof.

2. A hollow metal sill-bar adapted to seat on its top a window-pane and open to the circulation of air through it from its outer side below said top to its inner side behind the same. and a stopebar for confining said pane at its lower edge, having a forward depending lip-and a rear depending iange and secured on said bar to engage said lip with the outer edge thereof and present said fiange to the pane. i

3. A hollow metal sill-bar formed of an inner side and an outer side provided with a top affording a window-pane seat, said sides being united and forming between them lower outside and upper inside openings for the circu lation of ai r through said bar from its outer side below said top to its inner side behind the same.

4. A metal sill-bar formed of a hollow inner side and a hollow outer side whose top has a depending flange along its inner edge and affords a window-pane seat, said sides being united and communicating with each other for the circulation of air through the bar from its outer side below said top to its inner side behind the same.

5. A metal sill-bar formed of a hollow inner side and a vertically narrower hollow outer side whose top affords a window-pane seat,

vsaid sides being united and said top extending' in a plane below the upper edge of said inner side, said sides communicating with each other 'for the circulation of air throug'h the bar from its outer side below said top to its inner side behind the same.

6. A metal sill-bar formed of a hollow inner side and a hollow outer side whose top affords a window-pane seat, said sides being united and communicating with each other for the circulation of air through the bar from its outer side below said top to its inner side behind the same, and a bar secured on said top and forming a stop for the pane on its seat.

7. A metal sill-bar formed of a hollow inner side and a hollow outer side whose top affords a window-pane seat. said sides being united and communicating with each otherl for the circulation of air through the bar from its outer side below said top to its inner side behind the same, and a platform-support extending 'from said inner side.

8. A metal sill-bar formed of a hollow inner side with ribs at intervals on one surface, and a hollow outer side formed with a top for seating a window-pane, having a depending fiange on its inner edge at which it is united to said ribs, with spacing-lugs uniting said sides at intervals along' their lower edges, said ribs and lugs forminginlet-sp'aces for the circulation of air through the bar, and a-stop-bar secured on said top and formed with a depending lug on one edge engaging the outer edge of said top and with a depending flange on its opposite edge for presentation to the windowpane.
